Stainless Steel Pipes / Tubings

Kaysuns is a top supplier of stainless steel pipes and tubings in China, we provides both seamless stainless steel tubings and welded stainless steel tubings. Austenitic stainless steel has austenite as its primary phase, our product covers full 300 series and duplex stainless steel, nickel-based alloy and super austenitic stainless steel etc. We are also ability to supply titanium alloy tube and copper alloy tubes in ASME / EN norms. All of our tubings are qualified and a third party inspection are available for them.

Cold Rolling and Cold Drawing

  • Cold Rolling is a preferred production process for high precision seamless tube.  Most of our heat exchanger tube and mechanical tube are made by cold rolling. This technique provides a high forming rate, narrow tolerances and good turnouts. Now the biggest diameter we can get is 114.3mm for this process.
  • Cold drawing is the general process for our tube and pipe. Pipe&tubes from this process can be got a a very narrow tolerance ranges, and keep the chemical element well. Additionally, the cold drawing process is the perfect choice for situations which place high requirements on the quality of the surface structure.
